Had overheating issue with van 3 months ago and blew heater hose - had it and thermostat replaced. Just began overheating again - used the old heater trick to dissapate engine heat and it worked. Two days ago, after 30 mile drive, overheated almost to max - liquid overflowing from cooling resivour. Let it cool and tried again - soon overheated again with cool air blowing from heater. Took to shop - they let it idle 30 minutes at a time and couldn't make it overheat, yet cool air still blowing from heater. Note: coolant liquid levels had been running low and would have to be topped off about once a week.
With all of this in mind, does this sound like a water pump issue? Is there any way to check to be sure? The shop mechanics finally got it to overheat on a drive - they're not sure it's the water pump because they seem to think there would be a broken belt associated with it, but truth is, they're not sure why it's overheating.
have the same problem?
